Nothing to do with oiks, that f & v for unvoiced and voiced th. Goes back to the Dark Ages. A village called Finglesham (shwa in ham) is actually derived from "thengel" which was a word for some sort of nobility. So someone told the scribes a th word with an f in it.

Also oik is an odd word - no-one seems to know the origin. I have a hypothesis though, that it was coined by public school classicists in the RAF from the Spartan word perioikoi (sp?) which meant the non-fighting allies around the city, on whose work the Spartan elite depended. The meaning and the attitude are the same, but the word has been shortened inappropriately - peri would better fit than the oik component which meant the central household.

Using the word in contempt of others is not fitting unless you are of a trained elite like the Spartans or the Few.
